Problems solved by technology

Most of the current energy storage solar heat pump systems are heat collectors, heat accumulators, and evaporators arranged separately, and phase change materials are filled in the heat accumulators to store energy using phase change latent heat. The system is relatively complicated and the manufacturing cost increases. Using the heat-carrying medium to extract heat from the heat accumulator as the low-level heat source of the heat pump, the heat loss of the secondary heat transfer is large, and because water is used as the heat exchange medium in the heat collector, the temperature inside the heat collector is high, and the heat loss is low. Big

Abstract

The invention discloses a multiple sources water heating system of integrated heat pump for heat collecting / energy storing / evaporating, which comprises a compressor, a water-cooled condenser, a heat collector / an energy accumulator / an evaporator, an air-source evaporator, a water pump and a water tank, wherein the heat collector / the energy accumulator / the evaporator is in parallel connection with the air-source evaporator, and in series connection with a refrigerant pipe of the compressor and the water cooled condenser to form a closed loop circuit, and the water-cooled condenser is in series connection with the water pump and the water tank via the water pipe to form a closed loop circuit. The heat collector, the energy accumulator and the evaporator that unify the system which is capable of removing the intermediate part of heat transfer. The system is capable of storing solar energy via latent heat from solid-liquid phase heat transfer to enable the water heater to work all-weather in high efficiency, and resolving problem of instability of system work due to intermittency of the solar energy. Using the solar energy as a low temperature heat source for heat pump to produce hot water is a breakthrough of the mode of heating directly of traditional water heater, further can overcome the defect of low operating efficiency of the heat pump in winter, thereby all-weather providing hot water for life steadily.

Description

technical field [0001] The invention relates to a heat pump water heating system, in particular to a composite source heat collection / energy storage / evaporation integrated heat pump water heating system, which belongs to the field of solar energy utilization. Background technique [0002] With the continuous growth of my country's economy and the continuous improvement of people's living standards, the demand for hot water supply in family life is becoming more and more intense, and the proportion of energy consumption in this area to the total energy consumption is also increasing year by year. my country is a country that is not rich in conventional energy sources. As the mainstream products in the market, gas water heaters and electric water heaters have added pressure to the already tense energy and environmental issues. As a high-efficiency energy conversion device, heat pump has obvious energy-saving effect, and is adopted by researchers and users at home and abroad, a...
